Cause: This error results when there is a failure in evaluating filtering policies related to dictionary words. The cause can sometimes be a memory allocation issue but the most common reason for the message is the system's failure to extract text from an attachment. Check the preceding log error messages to determine the cause of the error, then take the appropriate steps.
Resolution: If the error is caused by an attachment, disable non-plain text scanning.
Click Protocols > SMTP > Settings.
Under Content Filtering Settings, uncheck Enable scanning of non-plain text attachments for words in dictionaries. Click Save.
